This
whitepaper explains the top 10 reasons
to throw out the old PBX and replace it with a new software based IP
PBX. The
whitepaper also provides a brief explanation of what an IP PBX is, how
it works
in a computer network and how it integrates with VOIP providers and
PSTN
Gateways.

An IP
PBX is a complete telephony system that
provides telephone calls over IP data networks. All conversations are
sent as
data packets over the network. The technology includes advanced
communication
features but also provides a significant dose of worry-free scalability
and
robustness that all enterprises seek.

Enterprises
don’t need to disrupt their
current external communication infrastructure: An IP PBX is able to
connect to
traditional PSTN lines via a VOIP gateway - so an enterprise can keep
its
regular telephone numbers.
